1Eaſt to Weſt? And the annual motion of the Sun through the
Ecliptick, is it not on the contrary from Weſt to Eaſt?
How
then can you make theſe motions being conferred on the Earth, of
contraries to become conſiſtents?
SAGR. Certainly, Simplicius hath diſcovered to us the original
cauſe of error of this Philoſopher; and in all probability he
would have ſaid the very ſame.
SALV. Now if it be in our power, let us at leaſt recover
Simplicius from this errour, who ſeeing the Stars in their riſing
to appear above the Oriental Horizon, will make it no difficult
thing to underſtand, that in caſe that motion ſhould not belong

to the Stars, it would be neceſſary to confeſſe, that the Horizon,
with a contrary motion would go down; and that conſequently
the Earth would reoolve in it ſelf a contrary way to that
with the Stars ſeem to move, that is from Weſt to Eaſt, which
is according to the order of the Signes of the Zodiack.
As, in the
next place, to the other motion, the Sun being fixed in the
tre of the Zodiack, and the Earth moveable about its
rence, to make the Sun ſeem unto us to move about the ſaid
diack, according to the order of the Signes, it is neceſſary, that
the E arth move according to the ſame order, to the end that the
Sun may ſeem to us to poſſeſſe alwayes that degree in the Zodiack,
that is oppoſite to the degree in which we find the Earth; and thus
the Earth running, verbi gratia, through Aries, the Sun will
appear to run thorow Libra; and the Earth paſſing thorow the
ſigne Taurus, the Sun will paſſe thorow Scorpio, and ſo the
Earth going thorow Gemini, the Sun ſeemeth to go thorow
gittarius; but this is moving both the ſame way, that is
ing to the order of the ſignes; as alſo was the revolution of the
Earth about its own centre.
The error of the
Antagoniſt is
nifeſt, by
ring that the
nual and diurnal
motions belonging
to the Earth are
both one way, and
not contrary.
SIMP. I underſtand you very well, and know not what to
ledge in excuſe of ſo groſſe an error.
SALV. And yet, Simplicius, there is one yet worſe then this; and
it is, that he makes the Earth move by the diurnal motion about
its own centre from Eaſt to Weſt; and perceives not that if this
were ſo, the motion of twenty four hours appropriated by him
to the Univerſe, would, in our ſeeming, proceed from Weſt to
Eaſt; the quite contrary to that which we behold.
SIMP. Oh ſtrange! Why I, that have ſcarce ſeen the firſt
elements of the Sphere, would not, I am confident, have erred
ſo horribly.
SALV. Judg now what pains this Antagoniſt may be thought
to have taken in the Books of Copernicus, if he abſolutely invert

the ſenſe of this grand and principal Hypotheſis, upon which is
founded the whole ſumme of thoſe things wherein Copernicus
